ITIS taxpayers will be sent their annual tax liability (Notice of Assessment) as soon as it has been calculated by the Income Tax Office.
Taxpayers who do not pay their income tax through ITIS will receive their annual Notice of Assessment later in the year.
If a person has arrears of income tax the amount of arrears is added to the liability when the Tax Office calculates the effective ITIS rate. For one year of arrears the maximum effective rate is 25%, for two years 30% and for three or more years 35%.
